4 Claims. l

This invention relates to knitting machines and particularly to devices for facilitating the winding of yarn or thread onto a warp beam.

One of the difficulties encountered in the winding of yarn onto a beam or in warping a beam" as it is called in the trade, has been to hold the adjacent rolls of strands on the beam securely with the end portions of adjacent sections disposed in close proximity to each other. Such procedure is important in preparing a beam for knit'- ting certain articles, such as sweaters, where it is desirableto weave the fabric in web form in such manner that one longitudinal' half has the pattern reversed with respect to the other half, so that when the finished web is folded longitudinally the patterns will be superimposed upon each other. This is for the purpose of enablingI identical panels to be cut simultaneously.

In my copending application Ser. No. 83,137, filed March 24, 1949, now Patent No. 2,578,018`,` I have shown a form of warp beam collar which is suitable for accomplishing the foregoing problem, and the present invention constitutes an improvement of such collar construction, so as to minimize the overall thickness of the assembled collar and to eliminate any overhanging proand each of such collars includes a thimble 12 which has a central aperture 13 of a size suflicient to permit the thimble to be slid over the beam before the yarn is wound thereon.

The collar assembly includes a U--shaped plate section 15 and coacting plate IGlwhich when assembled provide an annular disc, as shown in Fig. 5, upon the thimble. To accomplish this, the thimble has a peripheral groove 1'1 into which portions of the respective plates engage and are firmly held Whenever the plates are locked together.

A plate formation which has been found to be satisfactory for accomplishing the present invention is illustrated in the various figures, wherein the plate 15 has a curved portion 20 which is substantially semi-circular in form andiis adapted to engage substantially one-half the peripheral portion of the groove 1'1, the portion 20 being adapted to fit snugly within the groove. The plate 15 has a recessed portion extending outwardly from the curved portion 20 and is defined by parallel walls 21 and 22 which are spaced apart a distanceisubstan'tially equal to the outside diameter of the thimble. Such walls may be jections which might interfere with the winding i of the beam.

Briefiy, the present invention includes a thim- 'ble which is adapted to be adjustably fastened to the beam, together with two coacting plate sectlons which are detachably connected to the thimble and are adapted to be locked into place by a looking device which presents no projecting portions that would be apt to interfere with the winding of the yarn onto the beam.

Referring to the drawings, Fig. 1 is a perspective view of a beam having collars thereon made in accordance with the present invention; Fig. 2 is a perspective view illustrating portions of the collar in position for assembly; Fig. 3 is a side view of one of the plate sections; Fig. 4 is an ex- -ploded side view illustrating the looking means -for the plate section; Fig. 5 is a side view of an assembled collar; Fgs. 6, 7 and 8 are scctions taken on correspondingly numbered lines as Fig. 45; Fig. 9 is a side view of a part of one of the f plate Sections and Fig. 10 is a top plan view of the fsection shown in Fig. 9 and taken in the direc- -tion indicated by the line 10-111 in Fig. 9.

In the drawings, I 0 indicates a warp beam ,onto which strands 11 are to be wound. Collars embodying the present invention embrace the "beam at spaced intervals to limit the extent, -axially of the beam, for placement of the yarn connected to the curved portion by arcuate portions 23 and 24 respectively.

The plate 16 has parallel edges 26 and 21 which flt snugly against the walls 21 and 22 and has a concave curved portion 28 at one end for snug fitting engagement with that portion of the thimble groove which is not occupied by the plate 15, and has` a convexly curved edge at the opposite end 29 so as to complete a clrcular disc whenever the plate 16 is assembled onto the plate 15.

To assist in retaining the plates 15 and 16 in interlocking engagement. I have shown tongues 30 and 31 adjacent the outer end of the plate 15 which are adapted to engage corresponding grooves 32 and 33 respectively in the plate 15. The tongues and coacting grooves are disposed within the confines of the faces of the coacting plates, as shown in Fgs. 7 and 8, whereby the outer surfaces of the plates are substantially coplanar at the completion of the assembly.

To lock the assembled plates together, I have shown a threaded aperture 35 (Fig. 4) which may extend inwardly from the outer peripheral portion of the plate 15 at an inclined angle to the wall 21 and which is adapted to receive a set screw 33 which may be turned therein by means of a wrench illustrated at 3'1. A shouldered recess 38 is positioned on the edge 26 of the plate 16 in alignment With the aperture 35, whereby the screw 36 when tightened eflects a. satlsfactory interlock between the two plates. If desired, the plate l may have a bulbous enlargement 39 as shown in Fig. 7, so as to provide adequate wall strength for the aperture 35. This enlargement occupies only a relatively small part of the plate and, being rounded, does not interfere with the placing of the strands onto the beam.
